Three cases of stroke reported in young adults following covid-19 vaccination

Clots in the arteries (arterial thrombosis) are the most common cause of stroke (ischemic stroke) and have been reported in detail for the first time in young adults who received the Oxford–AstraZeneca covid-19 vaccine in a letter from UK stroke specialists published online in Journal of Neurology Neurosurgery & Psychiatry.

Researchers use special "micro-grid" recording device to measure hippocampus activity

Researchers at UC San Francisco have observed a new feature of neural activity in the hippocampus - the brain's memory hub - that may explain how this vital brain region combines a diverse range of inputs into a multi-layered memories that can later be recalled.

Laser procedure for pediatric patients with epilepsy holds advantages over traditional brain surgery

Using a laser for a rare brain surgery to treat drop seizures, which cause a child with epilepsy to suddenly fall, holds some advantages over a traditional open craniotomy, including shorter hospital stays for patients, a study led by UT Southwestern researchers indicates.

New imaging technique captures real-time brain motion in stunning detail

Magnetic Resonance Imaging (MRI) images are usually meant to be static. But now, researchers from Mātai Medical Research Institute (Mātai), Stevens Institute of Technology, Stanford University, the University of Auckland and other institutions, report on an imaging technique that captures the brain in motion in real time, in 3D and in stunning detail, providing a potential diagnostic tool for detecting difficult-to-spot conditions such as obstructive brain disorders and aneurysms - before they become life threatening.

Sodium fluorescein may improve the safety and outcomes of vestibular schwannoma surgery

Removing a vestibular schwannoma -; a slow-growing, benign tumor that develops in the nerves connecting the inner ear to the brain -; is a delicate procedure. Surgeons must differentiate the tumor from nearby nerves, arteries, and other intracranial structures.
